Definitions

  • This invention relates to a process of manufacturing pneumatic tires made of synthetic elastomers, particularly of polyurethane, and comprising an inner tire layer, a tire body, which is anchored in the inner tire layer by means of bead cores, a belt, and an outer tire layer provided with a tread portion, and to apparatus for carrying out that process.
  • the main part of pneumatic tires consists of the tire body and belt, which reinforce the pneumatic tire in order to take up the internal pressure of the tire and any deformation of the tire in operation so that the tire will not be excessively deformed.
  • the tire body of conventional pneumatic tires is made from cord strips, which are cut in the desired width from webs of fiber or steel cords coated on both sides with rubber or rubberlike elastomers and are subsequently adhesively joined to form strips in which the direction of the cords has been changed.
  • the cut edges of these strips are folded around and adhesively joined to so-called bead cores, which are structural parts provided for that purpose on both sides of the tire.
  • bead cores which are structural parts provided for that purpose on both sides of the tire.
  • a disadvantage of the tires made by that process resides in that adjacent to the cut edges of the cord strips which have been reversely folded around the bead cores the side walls may be disintegrated or seriously damaged under excessive loads or when the tire has become deflated.
  • U.S. Pat. No. 3,606,921 describes a different process, in which a steel or fiber cord or cable is wound around a toroid to form a radial winding. That process depends on the use of special wheel rims, which have been designed only for such tires, and the process can be used only to make large tires for very heavy special vehicles.
  • the object is accomplished according to the invention substantially in that the tire body is made in that a cord or cable is wound radially from one bead core to the other bead core over the periphery of a forming core but spaced from the surface of said forming core while being anchored in alternation on at last one of the two bead cores provided on both sides of the tire by being completely slung around each bead core, that a peripherally extending belt is applied, and that finally the outer tire layer and the tread portion are applied.
  • the outer layer and the inner layer of the tire can be manufactured together in a combined casting or injection procedure.
  • the inner tire layer made in the first operation may preferably be provided on its outside surface with elevations, particularly annular elevations, which when the radial reinforcement has been applied ensure that the liquid material used for injection molding or casting will more effectively flow through the body so that the latter is anchored more effectively.
  • each portion of the tire body will be under the same initial stress so that the deformation can be taken up uniformly by the entire tire body.
  • the peripherally extending belt can be made in that cable or cord is wound in a peripheral direction.
  • the tire body and the belt may be combined so that the tire will meet specified strength requirements. It is sufficient to provide a mold and mold core which correspond to the desired size of the tire.
  • the reinforcement can be varied within a wide range by the selection of the distance between adjacent reinforcing plies.
  • the anchoring of the cable or cord on the bead core by an operation which is similar to crocheting permits a fast and economical making of a tire body which is free from the drawbacks that are inherent in conventional tire bodies because of their adhesive joints.
  • the strength properties of the tire body depend only on the dimensions of the cable or cord plies and on the spacing of such plies, and there is no adhesive joint.
  • the cord or cable can be anchored to the bead core in a particularly simple manner in that the cable or cord used for a radial reinforcement is laid under constant tension from one bead core to the other over the periphery of the inner tire layer and is slung around each bead core so as to form a loop, the inner tire layer is advanced in the peripheral direction, and a new loop is formed in an operation which is similar to crocheting in that the cable or cord laid over the periphery of the inner tire layer is threaded through the previously formed adjacent loop and is thus connected to the bead core.
  • the latter are preferably spaced from the outside surface of the inner tire layer. This can be accomplished by the use of spacers, which are spaced around the periphery of the inner tire layer, or by the provision of a bead core holder on the mold. Each spacer provided on the outside surface of the inner tire layer may be removed when the cable or cord has been laid around the adjacent portion of the bead core. In that case the desired tension of the cable or cord can be exactly controlled.
  • the bead cores can be anchored on the periphery of the inner tire layer, e.g., by cables or wires so that the bead cores will be held in position in the mold.
  • the outer mold may be provided with interior parts which cooperate with the bead cores so as to hold them in position and to ensure a desired initial stress of the radial reinforcement.
  • the inner tire layer has a curved portion which bulges laterally outwardly beyond the bead core to a radius which is larger than the radius of the bead cores
  • the tension of the cable or cord can be adjusted when the cable or cord is spaced from the outside surface of the inner tire layer.
  • the resulting tension will then be exactly as high as the tension which is desired when the bead cores have been secured to the outside surface of the inner tire layer.
  • reels on which the cable or cord has been wound can be moved around the bead core and simple machines may be used for that purpose.
  • the cable or cord, starting from one bead core is passed in a loop to the other bead core, the loop is slung around the other bead core and the free end of the cable or cord is threaded through the loop so as to form a knot, and this sequence is repeated around the periphery of the bead core until the starting point has been reached and any protruding ends of the cable or cord are cut off.
  • cables or cords extending parallel to each other and transversely to the peripheral direction are applied in each step.
  • the trailing end of the cord or cable is first tied to one bead core so that a free end remains in a length which is approximately twice the peripheral extent of the bead core.
  • the cord or cable is laid over the inner tire layer to the other bead core and is slung around the same so as to form a loop, which is then returned to the first bead core.
  • the loop which has been returned is slung around the first bead core and is secured to it by means of the free end of the cord or cable with formation of a knot.
  • the second part of the cord or cable loop is laid once more over the inner tire layer and slung around the second bead core with formation of a loop, which is returned to the first bead core.
  • the cable or cord may be slung around the second bead core from the outside inwardly and from the inside outwardly in alternation.
  • the loop which has been returned to the first bead core is again tied together with the free end portion with formation of a knot.
  • the sequence is repeated throughout the periphery of the inner tire layer and the ends of the cable or cord are cut off when the last knot has been formed.
  • the operation which has been described is basically known for upholstering furniture.
  • a mold assembly for casting or injection molding comprises a central mold core and at least two sets of outer mold sections.
  • the mold sections of the outer set are preferably provided on the inside with annular recesses for molding the annular elevations of the inner tire layer.
  • the mold sections of the second set conform to the outside pattern of the finished tire.
  • the tread portion is preferably molded at the same time as the breaker.
  • the cable or cord may consist of wires of synthetic fibers or steel, e.g., of polyamides.
  • Spacers may be provided for properly locating the peripherally extending reinforcement so as to ensure the desired position of the belt in the tire.
  • the spacers have such a cross-sectional shape that they at least partly embrace the belt and have on one side an opening through which the belt can be inserted. In that case the belt need not be tensioned by the spacers because the belt is located in the desired position by the embracing portions of the spacers.
  • the spacers may then be designed so that the width of the web portion or the inside width of the cross-section which receives the belt is selected so that it can accommodate a belt having a width which is at least 10% and preferably not in excess of 50% of the width of the tread portion of the tire.
  • Such a design will be particularly desirable in view of the requirements to be met by the reinforcements of a tire which has been cast or injection-molded in one operation.
  • the distance from the points of contact between the belt and the webs to the inside surface of the inner mold member is preferably about 50% of the smallest wall thickness of the tread portion of the tire.
  • a tire provided with such reinforcement possesses a tire body which has a virtually constant wall thickness and which is adjoined by the tread portion which has been cast or injection-molded and consists of the same material.
  • Plastic materials which may be used to make the vehicle tire according to the invention include polyurethane, which is preferred, also 6,6 polyamide, polyvinylchloride, polyethylenes or the like as well as rubber mixes which can be injection-molded or cast. The use of these plastic materials is permitted mainly because an appropriate reinforcement is provided.
  • FIG. 1 is a transverse sectional view showing a tire which has been made according to the invention.
  • FIG. 2 is a perspective view showing the arrangement of the cord or cable; the mold core has been omitted for the sake of clearness; FIG. 2 shows diagrammatically also a compensating device.

  • circumferentially extending reinforcements 5 are indicated below the tread portion 6.
  • FIG. 2 is a diagrammatic illustration how the cord or cable 3 is withdrawn from a supply reel 7 and guided by rollers 8, 9, 10, which serve to maintain the cord or cable 3 under a constant tension.
  • the intermediate roller 9 is loaded by a weight 11.
  • the intermediate roller 9 will rise in the direction of the arrow 12 and will actuate the limit switches 13 and 14.
  • a brake 15 releases the supply reel 7 for rotation so that the roller 9 can descend as far as to the limit switch 14, which then causes the brake 14 to be applied.
  • the cord 3 is laid around the bead cores 2 with formation of loops 16 and is connected to the bead cores by an operation which is similar to crocheting.
  • the cord 3 is laid from the left-hand bead core 2 over the periphery of the inner tire layer, not shown, and is threaded through the loop which has been formed in the preceding step and laid around the right-hand bead core 2.
  • a new loop is formed, through which the cord is threaded when it has been laid over the periphery of the inner tire layer as far as to the other side and threaded through the loop 16 at the left-hand bead core 2 and laid once more over the periphery of the inner tire layer.
  • the mold core may be provided on its periphery with peripherally extending ribs 17, which space the tire body from the recessed portions 18 of the peripheral surface of the mold core.
  • the spaces which have been left may be filled by the molten material which is being poured.
  • FIG. 4 shows an alternative, in which the mold core 1 is provided with a covering 19 formed with ribs 20. That covering 19 may be made from the same material as the tire, such as polyurethane, and constitutes the inner tire layer.
  • FIG. 5 shows an inner tire layer 21 which has been cast from polyurethane.
  • the bead cores 22 are embraced by cables or cords 23.
  • the side wall parts 25 and the tread portion 26 are applied.

  • the cables or cords 23 have been laid in alternation around the two bead cores 22 disposed on opposite sides of the inner tire layer 21.
  • the bead core 22 consists of a twisted steel cable closed in itself and the cables or cords 23 consist of cables or wires of plastic material.
  • the cables or cords 23 extend over the periphery of the inner tire layer to the other bead core 22 and from the latter back to the first wire bead 22.
  • the cables or cords 23 are secured to the bead cores 22 in the manner illustrated in FIG. 2 by an operation similar to crocheting. Alternatively, they may be secured in the manner which will now be described with reference to FIG. 9.
  • FIG. 7 shows spacers 28, which are disposed between the bead cores 22 and the inner tire member 21 and which are pulled out whenever the cables or cords 23 being laid around the bead cores 22 have come into contact with the spacers 28.
  • FIG. 8 shows the bead core 22 in contact with the inner tire layer 21 and in a position 22'.
  • the bead core 22 cannot be extended or can be extended only very slightly.
  • the distance a from the bead core in position 22' to the longitudinal center plane of the tire is such that the length of the reinforcing elements b extending from the bead core 22 on one side of the inner tire layer 21 to the bead core in position 22' on the other side of the inner tire layer 21 equals the distance between the bead cores 22 when they are both in contact with the outside surface of the inner tire layer.
  • FIG. 8 shows also anchoring members 29, which become embedded in the inner tire layer 21 as it is cast.
  • the two ends of the anchoring member 29 are connected, e.g., by means of knots 30, so as to enclose the bead cores 22, which are thus held in engagement with the inner tire layer.
  • the cable or cord 23 is slung completely around the bead cores 22.
  • the process can be carried out in a simple manner in that a cable or cord loop is passed between the outside surface of the inner tire member 21 and the bead core 22 and laid around the bead core 22 and the free end of the cable or cord 23 is then threaded through the loop.
  • FIG. 9 shows how the cord or cable can be secured to the bead cores in a different manner, which is similar to a stitching operation or to a weaving operation using a weft. In this way, there will result each time a knot around the bead core.
  • the cord or cable 35 is secured at 37 to a first bead core 36 by a double knot in such a manner that a long free end 38 is left.
